Brief exposure to some components made them harder to identify in mixtures. A 2017 study also found that a shared smoky note could become prominent.

Women’s preferences showed some consistency even for fresh body-odor samples collected from the same men three months later. Comparisons with fragrances and facial photographs explore preference stability.

An fMRI study of a jasmine model mixed with indole found that pleasantness, unpleasantness, and intensity were represented differently across brain regions, even when the mixture felt pleasant overall.

A study broadly examined functional differences between olfactory receptor variants. Less responsive OR10G4 variants were associated with weaker, more pleasant guaiacol ratings, but not with the same pattern for vanillin compounds.

Sweat collected during a positive mood produced differences in receivers’ heart rate and idea-generation tasks compared with neutral-condition sweat. The study also compared physiological and perceptual responses with added perfume.

After synthetic body odor, participants were slower to press a key to approach an on-screen perfume bottle. Alongside a sound experiment, the study explores behavioral measures of preferences.

Matching perceived intensity across a broad range of odorants made mixtures smell similar without shared ingredients. Tests explored naming, six-month memory, and rose recognition.

Physiological responses distinguished broadly different odors but were less sensitive to perfume preferences. Facial muscles retained small differences.

Eight women exposed to the same odor at home for two weeks became less sensitive to it. The study examined differences from short-term adaptation and recovery after removal.

Nineteen people rated the same odor for 10 minutes. Focusing on it slowed the initial decline in intensity compared with counting sounds, with later periods of renewed perception.
